Multirate Digital Signal Processing for Software Defined Radio (SDR) Technology
In the past, radio systems were designed to communicate using one or two wave forms. As a result, two groups of people with different types of traditional radio were not able to communicate due to incompatibility. The need to communicate with people using different types of equipment can only be solved by using software defined radio (SDR). SDR is a wireless device that works with any communication system, be it a cellular phone, a pager, a WI-FI transceiver an AM or FM radio, a satellite communications etc. In both hardware and software Digital Signal Processing (DSP) techniques are used to design a real time system. For SDR applications involving high complexity, it becomes impossible to stay with single sampling rate and so altering the sampling rate at different stages is required for low cost DSP hardware. Thus variable sampling rates i.e. Multirate Digital Signal Processing is required.
